Objective: The climate crisis is the defining issue of our time. Educational and developmental psychologists can make clear and important contributions to addressing this existential threat. The articles in the Climate Crisis Special Issue take on the issue of climate change from multiple angles, with varied populations, using different research…

Jeremy Sawyer recounts that, after Lev S. Vygotsky's death, Jean Piaget conceded the Russian psychologist correctly understood the social origins, functions, and developmental trajectory of children's egocentric speech (now called private speech) but dismissed this work as irrelevant to children's egocentrism or nondifferentiation of perspectives.…

In this commentary on the special issue on emotional development, I focus on the papers by Holodynski and Seeger (2019) and by Hoemann, Xu, and Barrett (2019). I suggest that although understanding our emotions is an important part of emotional development; emotional development cannot be reduced to concept development, even when such concepts…

Computer vision algorithms have made tremendous advances in recent years. We now have algorithms that can detect and recognize objects, faces, and even facial actions in still images and video sequences. This is wonderful news for researchers that need to code facial articulations in large data sets of images and videos, because this task is time…

This study aimed to facilitate a better understanding of the psychological characteristics of maltreated children by comparing attachment representations between maltreated and non-maltreated pre-schoolers. Participants included 46 maltreated and 48 non-maltreated (children for whom evidence of maltreatment has not been identified or reported)…

I argue that emotion research needs formal (mathematical) theory to address two central questions. How does evolution shape mechanisms of emotion development across generations, depending on environmental conditions? How do these mechanisms generate emotions, based on lifetime experience and current context? Formal modeling enables researchers to…

The specific strategies that individuals use to regulate their emotions have shown strong associations with various indices of well-being. However, theoretical accounts suggest that strategy use, and the associations between strategy use and well-being, may change across the life span. Attempts have been made to assess whether levels of strategy…

Questions concerning longitudinal stability and multi-method consistency are critical to temperament research. Latent State-Trait (LST) analyses address these directly, and were utilized in this study. Thus, our primary objective was to apply LST analyses in a temperament context, using longitudinal and multi-method data to determine the amount of…

In this article, the author states that it is a delight to walk into a Montessori classroom to the hum of children engaged in a variety of activities, especially when there is an accompanying feeling of joy and happiness. In desiring the peaceful calm of the classroom, educators may inadvertently hinder the joy, enthusiasm, and imagination that…

We argue that video game play may meet Larson's (2000) criteria for fostering initiative in youth, and thus, may be related to positive outcomes such as flow, cooperation, problem solving, and reduced in-group bias. However, developmental and social psychologists examining adolescent video game use have focused heavily on how video games are…

The fields of psychology and human development are experiencing a resurgence of scientific inquiries about phenomena that unfold at the level of the individual. This article addresses the issues of analyzing intraindividual psychological/developmental phenomena using standard analytical techniques for interindividual variation. When phenomena are…

As social media use is rising among adolescents, the issue of whether this use leads to positive or negative outcomes warrants greater understanding. This article critically reviews the literature related to this important topic. Specifically, we examine how social media use affects social connectedness in terms of three elements of adolescent…

Behavioral inhibition is a temperament characterized in infancy and early childhood by a tendency to withdraw from novel or unfamiliar stimuli. Children exhibiting this disposition, relative to children with other dispositions, are more socially reticent, less likely to initiate interaction with peers, and more likely to develop anxiety over time.…

How do schooling years impact children's lives, in rural and urban settings? Why do some children have lower self-esteem than others? What kinds of conflicts do adolescents experience in their search for identity? Why are some teachers able to understand the importance of ensuring the well-being of children while others do not? Does the emotional…

We investigated longitudinal predictors for disordered eating from early adolescence to young adulthood (12-34 years) across gender and different developmental phases among Norwegian young people. Survey data from a population-based sample were collected at four time points (T) over a 13-year time span. A population-based sample of 5,679 females…
